这是我在R上的代码，它不断给我留言

  

错误：意外＆＃39;}＆＃39; in＆＃34; }＆＃34;

当我尝试运行它时。问题是什么？我检查了括号的余额，并根据论坛它应该工作。

n = 1 
while(n < 3) { 
    i = 2
    while (i < 17) {
        data_freq = data_pourcentage %>%
            filter(groupe = i & groupe = n) %>%
            mutate(pourcentage = sum(freq)) %>%
            mutate(pourcentage = freq / pourcentage)
        data_pourcentage = left_join(
            data_freq, 
            data_pourcentage, 
            by = c(
                "sujet", "groupe", "identification", 
                "cristallisation", "valence", "freq")
            )
        i = i + 1
    }
    n = n + 1
}

Answer 1

过滤器命令中的&是问题所在。只需filter(groupe = i)，一切正常。要合并更多组件，请使用filter(groupe= c(i,n))。

n = 1 
while(n < 3) { 
    i = 2
    while (i < 17) {
        data_freq = data_pourcentage %>%
            filter(groupe = c(i,n)) %>%
            mutate(pourcentage = sum(freq)) %>%
            mutate(pourcentage = freq / pourcentage)
        data_pourcentage = left_join(
            data_freq, 
            data_pourcentage, 
            by = c("sujet", "groupe", "identification", 
                   "cristallisation", "valence", "freq")
            )
        i = i + 1
    }
    n = n + 1
}
